Opened to a slimy pool:(

45 is not good if you have a vinyl pool, even if your CYA is over 100. It might bleach your liner, if the measure is correct.

Try mixing 1/4 cup of pool water with 3/4 c of distilled water (Steam distilled is sold at most supermarkets and it's cheap) and see if you get around 10ppm

You may want to leave it open to the sun, or drain some water and add some.

But mostly you need to start by confirming that number.

It WILL come down if you just leave it open to the sun. There is a chlorine neutralizer available (It's in the PS232 to PS234 and TFP test kits, but just a few drops), but I don't know about its usage in pools.

Hello. my FC is down to 12 maybe-

as im waiting for my Taylor drops i stopped by the local poo store and picked up this-

OTO 394 CHLORINE TEST BROMINE TEST. the pool store said it is for the free chlorine test and is the same as the taylor test.

is that true?

Close enough for government work!

OTO doesn't really measure over 5ppm unless you use the "patented CarlD Shotglass Method" (do a search on PF for it).

We all use the FAS-DPD method of measuring which goes to at least 50, some say 100ppm.
